Follow-up self-review on the previous head found that the per-mapping last-consumer scan made `finalize_chunk()` O(N²) for wide schemas. Fixed in 7ab045563f1: queries without Path Slots keep the original linear/allocation-free path, while Path queries precompute the last consumer per file-local carrier in expected O(N). Added `FinalizeWithoutVariantPathRetainsDirectTransfer`; the focused ASAN suite now passes 12/12, including the existing 1 MiB root-first Path Slot no-copy regression. -- This is an automated message from the Apache Git Service.
